C_DBADM_2404 Exam Dumps : SAP Certified Associate - Database Administrator - SAP HANA

When scaling down an SAP HANA Cloud, SAP HANA database instance, the following resources are affected:

• vCPUs: Reducing the number of virtual CPUs will decrease the processing power available to the database instance.
• Memory: Lowering the memory allocation impacts the amount of data that can be stored in-memory, affecting performance and capacity.

References=SAP HANA Cloud service documentation provides details on the impact of scaling operations on database resources, emphasizing the change in compute and memory resources.

Provisioning SAP HANA

The supported scenarios for a database copy using backup and recovery from a source machine to a target machine include:

• The source system and target system have different SIDS: This scenario is supported as it allows the target system to be configured with a different system identifier, which is common during cloning or migration processes.
• The source system release version is higher than the target system: This is feasible provided that the features and data structures used in the higher version are compatible with the target system, allowing for downward compatibility in terms of data recovery.

References=These scenarios are outlined in SAP HANA's technical and administration documentation, which discusses the conditions under which backup and recovery can be effectively utilized across different systems.

Backup and Recovery

You can resume the failed recovery of your productive SAP HANA tenant database in the following situations:

• An aborted recovery of a delta data backup: Resuming from a delta backup is possible because these backups capture changes since the last full or another delta backup, allowing the recovery process to continue from the last successful point.
• An aborted recovery of a log backup: Log backups contain all the transactions since the last log or data backup. If the recovery from these backups is interrupted, it can be resumed because the log contains all necessary information to bring the database to a consistent state up to the point of failure.

References=SAP HANA backup and recovery documentation explains the mechanisms and capabilities of the database's recovery features, including scenarios where recovery processes can be resumed after interruption.
